Techniques

When I was in my youth built the first time a guitar myself, I took cheap plywood, it was just there! I just did not think about what wood I take and in what grade should I use it? On this point I'm away for a few years. The more I looked into it, the less clear were the answers.

Does this sound familiar: You play a beautiful number, possibly even just running the recording recorder - and anything is booming here. Hardly the guitarist or bassist turns a little, already also the hum is less.
